I don't have Archicad in front of me at the moment to test anything.
Are you opening the schedule from the Project Map or the view map>
Try the Project map - make sure what you want to change is visible on plan and then open the schedule from the Project Map.
That should open the schedule with the same settings as your plan - i.e. if you can edit it in the plan, you should be able to edit it in the schedule.
When you open a schedule from the View Map, it has its own settings, and this may be preventing you from editing the elements.
There are 2 buttons at the top of the schedule settings - select in 2D and select in 3D.
Are these greyed out by any chance?
